Genetic Algorithms are stochastic optimization methods where solution candidates, complying to a specific problem representation, are evaluated according to a predefined fitness function. These approaches can provide solutions in various tasks even, where analytic solutions can not be or are too complex to be computed. In this paper we will show, how certain set of problems are partially solvable allowing us to grade segments of a solution individually, which results local and individual tuning of mutation parameters for genes. We will demonstrate the efficiency of our method on the N-Queens and travelling salesman problems where we can demonstrate that our approach always results faster convergence and in most cases a lower error than the traditional approach.

The COVID-19 pandemic has had disproportionate economic consequences on the urban poor, particularly on young people living on the streets. As the pandemic moves from acute to chronic phases, novel methodologies can be used to rapidly co-produce outputs and share learning opportunities with those living in urban poverty. A “story map” focusing on the effects of the pandemic and lockdown was co-produced by UK researchers with street children and youth and practitioners in Harare, Zimbabwe in June 2020. Story maps are web applications combining participant-generated visual media into online templates, with multimedia content supported by narrative accounts. This story map reveals young street participants’ experiences of lockdown, including the effects on their livelihoods, sources of food and support networks. Its purpose is to tell the “story” of street lives, and to provide an advocacy tool and learning resource for policymakers, academics and practitioners working with young homeless people.
